SCX CX120 000 002 The New World Standard Crawler Crane
The New World Standard Take A Close Look. The SCX12002 Sets New Standards of Higher Crane Productivity And Profitability More Than Ever. Multiple wetdisk brake Dru Reduction gear unit Hydraulic otor SCX12002 As the second unit, Hitachi and Suitoo have created the New World Standard Crane of 120t class achine. Developed along the concept thees of "siple, refined and reliable", the SCX12002 offers new levels of safety, operability, durability and ease of aintenance. Advanced clutchless ultiple wetdisk brake is well designed, and ensures continuous heavyduty operation. The winch uses a ultiple wetdisk brake, and a forcedoil cooling syste is designed to sustain brake perforance even in continuous heavyduty operations, such as haer grabing. This brake syste is designed to provide reliability while requiring no aintenance. Also, a newly developed echanis is used on this brake design to reduce drag resistance and it realizes a sooth frictionoff between discs while a highviscosity hydraulic oil is used as standard, contributing to longer lift of hydraulic pups and otors. With a new negative brake of springapplied/power hydraulicallyreleased type applying dynaic hydraulic pressure for its release control, an effective braking can be done under an extree light foot pedaling, and it accordingly results in greatly reducing operator fatigue, especially during winch freefall operation under duty cycle applications. Further, the use of negative brake syste aintains a high level of brake safety even if a hydraulic pressure drop in the circuit happens. Powerful winch dru with bigger line pull. The SCX12002 is really a versatile achine, and certainly perfors not only liftcrane/luffing towercrane works but also duty cycle works under clashell, haer grab and dragline applications with bigger line pull of 196kN < 20t > as axiu with 26 dia. cable. In addition, by eploying a speciallytailored power increase control, the engine always axiizes its output under any load condition in whole range of engine rp. Optional third dru. A third dru is optionally available under the sae specifications as that of two ain operating drus, and it accordingly enables to efficiently perfor heavy duty works under an 196kN < 20t > line pull. New negative brake syste uch reduces operator fatigue and enhances safety. Pressure reduction valve Brake pedal An aluinuake oil cooler. For not only corrosion resistance but also high cooling efficiency, an aluinuake oil cooler is provided in front of engine radiator. 2 3
Linkage echanis Cab large sliding door. For an easy entry and exit to and fro the cab, a swinglink type cab large sliding door is well designed. Optional airconditioner of outsideairintake type. For good airconditioning wih fresh air, an outsideairintake type airconditioner is optionally available. A good swing speed control design. Max. swing speed can be steplessly controlled thru an easy dialing for sooth swinging for all kinds of work and operations like "higher hook hoisting and lower swing speed" in a high lift working. Slidable control station and operator seat. To set ost of suitable operator position, both right and lefthand control stations are designed to siultaneously slide 60 back and forth together with operator seat, and operator seat is able to slide 80 independently too. A high operation ease with speciallytailored EPC syste. Thanks to unique EPC syste, an easypreciseinute control of engine rp and pup discharge fro in. thru ax. is actually possible at the sae tie by siply twisting the grip. Archair control station with dru rotation sensors. An archair control station is provided for a good, easy and cofortable operation. In addition, archair control levers of two ain and boo hoist drus each fit the dru rotation sensor to let operator sense a dru rotation speed decrease gradually according to the extent of the load applied to the hoist cable, and it results in ore safety lifting work, especially in blind condition. Siplified instruent panel. For operator convenience, all of switches and controllers are gathered in a lefthanded instruent panel. The New World Standard SCX12002 JobProven Controllability and Operator Cofort Newly designed cab with increased visibility. Functional layout of controls, including archair control levers, iproves visibility forward, rearward and sideward. And, it accordingly results in enhancing operating ease under operator cofort with a natural position. 4 5
The New World Standard SCX12002 Pays a keen attention to safety, transport and environent too. Safety Newlydesigned Load Moent Indicator. An easytoread LCD graphic display panel is well designed on a new Load Moent Indicator (LMI) with setting ease of viewing angle. In addition, no zeropoint adjustent, and data input thru interface counterindication/ essage on display panel are available for easier and certain settings of operating conditions and LMI functions. LMI autoatically sets frontend att. erection ode with letter essage. In the range out of crane working area, the LMI display panel autoatically indicates "Now, out of crane working range" with a rigging instruction, and it is available to lift frontend att. off ground without the influence of LMI safety functions, and, after frontend att. is lifted over the range of crane working area, LMI safety function gets back autoatically for safe erection work. Optional lifting height indication function. For ore safe lifting work, especially in blind condition, it is optionally available to indicate the lifting height above ground or depth below ground on display panel of LMI. Boo speed slowdown function. This function is available just before autoatic stopping at both upper and lower side liits of boo angle to prevent a shock even though control lever is still at hoisting/lowering position. This function is also available when overloading. Independent lever lock. Each lever can be locked independently to prevent absentinded isoperation. Autoatic dru pawl locking device. On boo hoist dru, it is designed to autoatically lock and release dru pawl when control lever just returns to neutral position, and just actuates. Fool proof shutoff syste. To insure safety when the operator leaves the cab, a ain hydraulic shutoff switch is located in the cab exit to deactivate and lock the hydraulic syste. Swing/travel alars. These alars alert work crew around the acine when swinging and/or traveling to keep clear for safety. Eergency achine stop buttons. In the case of an eergency, the operator can stop the achine by the pressing buttons, located at left front and right rear. Mobility Transportability Counterweight with horizontallyspit design. It is able to load boo extension(s) onto counterweight when transport. And, the reversible stack is possible to reduce the tie for disassebling/assebling works. An assebling ease of crawler side fraes. Thanks to "hookon design" with hydraulic reoval jointpins, crawler side fraes can be easily assebled and disassebled on and fro carbody frae, and it accordingly result in a tie saving task. Environent The engine eets current EU Eission Regulations for OffRoad Diesel EngineStage 2, and Japanese Eission Standard for Diesel Construction EquipentStage 2, and the SCX12002 clears low noise levels as defined by Ministry of Land, Infrastructure and Transport of Japan under the new noise easuring ethods regulated by ISO. 6 7
